Front

What is the process called when molecules move across a membrane without the use of energy?

Back

Passive transport.

Front

What is the direction of molecule movement during active transport?

Back

From an area of lower concentration to an area of higher concentration.

Front

What is required for active transport to occur?

Back

Energy, usually in the form of ATP.

What happens to a red blood cell in a hypotonic solution?

Back

It swells and may burst.

Front

What is the role of ATP in cellular transport?

Back

ATP provides the energy needed for active transport.
